LTC3128EFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3128EFE is 38V, but it's recommended to keep it below 36V for reliable operation.
  • To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 2x the maximum output current, and a DC resistance of less than 100mΩ.
  • For optimal performance, keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise. Keep the inductor and diode away from the IC to minimize electromagnetic interference.
  • Check the input voltage, output load, and component values. Verify that the inductor is not saturating, and the output capacitor is suitable for the output voltage and current. Use an oscilloscope to measure the output voltage and current waveforms to identify any issues.
  • The LTC3128EFE is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
